Commit 496f2f93b1cc286f5a4f4f9acdc1e5314978683f ("random32: rename random32to prandom") renamed random32() and srandom32() to prandom_u32() andprandom_seed() respectively. Due to the volume of existing random32()callers, they were preserved as backword compatibility wrapper macros.

This patch series aims for finishing the naming transition and removingthe backword compatibility wrapper macros.

The naming transition is mainly simple substitution work for random32()and srandom32(). Furthermore, net_random() and net_srandom() are anotherwrapper macros for random32() and srandom32(). They also should berenamed to prandom_* while I'm at it.

This patch series also includes minor cleanup and bugfix which were foundwhile I was working on the substitution.
